Preferably, the transmission frame is an ATSC frame, and the access information for accessing the turbo stream for the primary service is included in a DFS (Data Field Sync).

Advantageously, said access information comprises decoding information for decoding a primary service turbo stream.

Advantageously, the turbo stream for the primary service is transmitted over a remaining data area after mapping the at least one turbo stream to the transmission frame.

Advantageously, the data comprises signaling information, wherein the signaling information is transmitted over the remaining data area after mapping the at least one turbo stream to the transmission frame.

Advantageously, the transmission frame comprises information indicating whether signaling information or a turbo stream for the primary service maps through the at least one turbo stream to the transmission frame and is then transmitted through the remaining data area.

According to another aspect of the present invention, there is provided a broadcast service transmission apparatus including: a packet generation unit for packetizing at least one data for at least one broadcast service according to a type of data; A turbo stream generating unit for generating at least one packetized data as at least one turbo stream; A transmission frame generator for generating at least one transmission frame having a predetermined size using the at least one turbo stream; And a transmitter for transmitting the at least one transmission frame, wherein the at least one turbo stream includes a turbo stream for a primary service that is scheduled to be processed first in the broadcast receiver, Access information for accessing the turbo stream is included in a predetermined area of the transmission frame.

According to another aspect of the present invention, there is provided a broadcast service receiving method including: receiving at least one transmission frame; Interpreting access information for accessing a turbo stream for a primary service scheduled to be processed first in a broadcast receiving apparatus from a predetermined region of each of the at least one transmission frame; Accessing a turbo stream for a primary service of each of the at least one transmission frame using the interpreted access information; And processing the turbo stream.

According to another aspect of the present invention, there is provided a broadcast service receiving apparatus including: a receiver for receiving at least one transmission frame; Interprets access information for accessing a turbo stream for a primary service that is to be processed first in a broadcast receiving apparatus from a predetermined region of each of the at least one transmission frame, A transmission frame processing unit for accessing a turbo stream for a primary service of each transmission frame; And a turbo stream processing unit for processing the turbo stream.

According to the present invention, since the primary service access information for accessing the primary service is located in a certain area of the transmission frame, the broadcast service receiving apparatus preferentially uses the primary service access information without processing the signaling information channel, It can provide hair service. Accordingly, when the broadcast service receiving apparatus provides a broadcast service, it must search for a signaling information channel in a transmission frame and access the respective broadcast services only after interpreting the signaling information channel. It is possible to shorten the waiting time.

According to the present invention, compared with the case where signaling information or primary service is allocated to a channel of a certain size and transmitted by including signaling information or data for a primary service in a remaining area of a transmission frame, The channel is not wasted, so that the broadcast channel can be efficiently used.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a protocol stack for a broadcast service according to an embodiment of the present invention.

A protocol stack for providing a broadcast service according to an embodiment of the present invention includes an application layer 110, a transport layer 120, and a physical layer 130. A separate layer may be further included in the protocol stack to efficiently utilize a broadcast channel for broadcasting service or to be suitable for mobile broadcasting.

The broadcast service according to an exemplary embodiment of the present invention includes a real-time service, an IP service, and an object service. Real-time services are used when video and audio are expected to be received and consumed in real time. The real-time service data type is additional information to be displayed together with video, audio, and A / V. IP services are extensive, include data casting and other IP data that is received in real time, and are services that are intended to be consumed in real time or consumed later. An object service is a service that includes multimedia data that is received at a certain point in time and is intended to be displayed later in response to the received control information. The broadcast service of the present invention also includes the case of configuring a broadcast program including at least one of the real-time service, the IP service, and the object service.

The application layer 110 includes real-time A / V, IP, application data including objects, and signaling information that constitute a broadcast service. The signaling information includes configuration information of at least one broadcast service transmitted through a transmission frame.

The transport layer 120 may be referred to as an encapsulation and packetization layer. The transport layer 120 provides application details and fragmentation information for application data. In the transport layer 120, each application data is encapsulated in units of elementary data having a predetermined type-specific syntax. An application stream which is a sequence of encapsulated packets is generated. Then, one application stream is created with packets of fixed length, or at least one application stream is multiplexed with packets of fixed length. In this specification, a series of packets of a fixed length generated in this specification is referred to as a turbo packet, and a sequence of turbo packets is referred to as a turbo stream. Each of the generated turbo streams is formed as a turbo channel, and is mapped to a deterministic frame structure and transferred to the physical layer 130. The deterministic frame structure means that the transmission frame has a certain size and format, such as an ATSC frame.

The service description information and the signaling information, which are descriptive information for each broadcast service, are formed into a signaling structure in a packetization layer, formed into a signaling information channel (SIC), and transmitted to the physical layer 130. In the physical layer 130, the location information of the signaling information channel (SIC) is included in a data field sync (DFS) in a transmission frame.

In order to provide a broadcast service having a protocol stack as shown in FIG. 1 in a broadcast service receiving apparatus, the following process must be performed. First, the DFS of the physical layer 130 is analyzed to confirm the location information of the SIC. Then, the broadcast service receiving apparatus accesses the SIC as indicated by the arrow 11 using the identified SIC location information. The SIC includes information on how many turbo channels a transmission frame is composed and configuration information (turbo channel decoding information, meta information, etc.) of each turbo channel.

The broadcast service receiving apparatus accesses a predetermined turbo channel as indicated by the arrow 13 using the information contained in the SIC, processes the turbo stream transmitted through the turbo channel, Data of the application layer 110 may be obtained. Although FIG. 1 illustrates accessing the primary channel through the SIC, other turbo channels may be accessed using the SIC. The data of the application layer 110 included in the turbo stream transmitted through the turbo channel is processed and a broadcasting service is provided.

A certain waiting time is required until power is supplied to the broadcasting service receiving apparatus and the broadcasting signal is received and the broadcasting service is provided through the above process. In order to solve the problem that the broadcast service is not provided until all of the signaling information channels (SIC) are analyzed, a "primary service" is defined for allowing the broadcast service receiving apparatus to process and provide the default . The primary service is a service intended for the user to watch at the highest priority on the broadcasting service provider side.

The turbo stream for the primary service goes through the same formation process as the other turbo stream, but the access information for accessing the primary service is located in a predetermined area of the transmission frame. In case of ATSC transmission frame according to ATSC standard, access information for accessing primary service is defined in DFS. Therefore, according to the embodiment of the present invention, the broadcast service receiving apparatus can access the turbo stream for the primary service directly from the DFS as indicated by the arrow 21 without going through the process of finding and processing the SIC have.

FIG. 2 is a diagram illustrating an area of a transmission frame to which a transport stream is allocated according to an embodiment of the present invention.

The transmission frame used in the present invention has a certain size and the size of each turbo channel for transmitting the turbo stream transmitted through the transmission frame has a certain size. Generally, since the size of a transmission frame is not a multiple of the size of a turbo channel, a data area of a certain size is continuously left after at least one turbo channel is allocated to a transmission frame. FIG. 2 shows that turbo packets are allocated to each of transmission frames # 0 to #n transmitted in a predetermined period, and data regions 210, 212, and 214 of a certain size are left. When transmitting the signaling information or the turbo stream for the primary service to the remaining data areas, unnecessary broadcast channels are not wasted compared with the case of allocating a signaling information channel (SIC) or a primary service turbo stream of a certain size to a transmission frame The broadcast channel can be efficiently used.

Signaling information or data for a primary service may be mapped to a transmission frame and transmitted as in other turbo streams. However, according to an embodiment of the present invention, the signaling information is formed by the SIC and the data for the primary service is formed as the primary service turbo stream, but may be transmitted through the data area remaining in the transmission frame. Since the remaining data data area of the transmission frame is generally smaller than the size of the conventional SIC and the size of the channel for transmitting the primary service turbo stream, the SIC and the primary service turbo channel are not limited to the size of the remaining data area of the transmission frame And then transmitted through a plurality of divided transmission frames.

As described above, there are two schemes in which signaling information or data for a primary service is transmitted through a transmission frame. The broadcast service transmission apparatus transmits first information indicating whether signaling information is transmitted through a separate channel-allocated SIC or a remaining data area of a transmission frame, and data for a primary service is transmitted to a primary channel The second information indicating whether the data is transmitted through the turbo stream or the remaining data area of the transmission frame may be included in a predetermined area of the transmission frame, for example, DFS. Since the broadcast service receiving apparatus preferentially interprets the DFS in the transmission frame, the broadcasting service receiving apparatus can quickly access the signaling information or the data for the primary service by using the first information and the second information.

The turbo stream generator 320 generates at least one packetized data as at least one turbo stream corresponding to one broadcast service. At least one packetized data may be generated as a turbo stream, and at least one packetized data may be multiplexed and generated as a turbo stream. For example, the turbo stream may be generated by multiplexing A / V1, IP1, and Object 1 shown in FIG. 3, respectively, after being packetized.

The at least one turbo stream includes a turbo stream for the primary service that is scheduled to be processed first in the broadcast service receiving apparatus.

The transmission frame generation unit 330 generates transmission frames having a predetermined size using at least one turbo stream.

Information for accessing the turbo stream for the primary service is included in a predetermined area of the transmission frame. In the case of a transmission frame in the ATSC system, the access information can be included in the DFS (Data Field Sync) and transmitted. The access information includes location information indicating the location of the primary service and decoding information for decoding the primary service turbo stream. However, in the case where the primary service is transmitted through the remaining data area of the transmission frame as shown in FIG. 3, when the broadcast service receiving device knows position information on the remaining data area, it is necessary to transmit the position information There will be no.

The transmitting unit 340 transmits the transmission frame. According to an embodiment of the present invention, transmission frames are sequentially transmitted through a predetermined channel according to a predetermined period, thereby providing a broadcasting service.

The signaling information may be transmitted through a signaling information channel (SIC) to which a separate channel for transmitting signaling information is allocated, such as a turbo stream channel for transmitting a general turbo stream in the transport layer. The position information of the signaling information channel SIC may be included in a predetermined position of the transmission frame. The location information of the signaling information may also be included in the DFS (Data Field Sync) of the transmission frame corresponding to the physical layer.

Alternatively, instead of allocating a channel for transmitting signaling information in the transport layer in order to transmit signaling information, the transport frame generator 230 may convert at least one turbo stream into a transport frame having a predetermined size The signaling information may be included in the remaining space after mapping.

The packet generator 310 determines how many turbochannels are allocated to a transmission frame periodically transmitted with a predetermined size to be generated by the transmission frame generator 330 and transmits the turbochannel And transmits information on the size to be allocated and remained to the transmission frame generation unit 330. The transmission frame generation unit 330 may generate a transmission frame by allocating a channel for signaling information to a transmission frame based on the information transmitted from the packet generation unit 310. [ If the size of the channel required for signaling information is larger than the remaining data area, the transmission frame generator 330 divides the signaling information to be transmitted into the size of the remaining data area, and then transmits the signaling information over a plurality of transmission frames.

Even if the primary service is transmitted through the remaining data area of the transmission frame, the transmission frame generator 330 generates the turbo stream for the primary service according to the service configuration mode determined by the packet generator 310, And then transmitted over a plurality of transmission frames.

The transmission frame generation unit 330 may include information indicating whether the signaling information or the primary service is transmitted through the remaining data area of the transmission frame in a predetermined area of the transmission frame so that the broadcasting service reception apparatus transmits So that the frame can be processed.
